Manchester United's Eric Bailly could have his European ban extended after Uefa opened disciplinary proceedings after his red card against Celta Vigo.
The Ivory Coast defender, 23, was dismissed after a brawl in the final minutes of United's Europa League semi-final aggregate victory on Thursday.
A direct red card carries a one-match ban - which means he will miss the final - but Uefa will determine whether to extend that at a hearing on 20 July.
His case does not qualify for appeal.
European football's governing body only overturns decisions made by the referee in cases of mistaken identity.
